This paper reviews several decades' worth of research on the topic of slat noise arising from
high-lift systems of commercial aircraft. A high-lift system is commonly used for providing …

Abstract The Delayed Detached Eddy Simulation (DDES) and Ffowcs Williams–Hawkings
(FW–H) analogy have been performed to describe the unsteady flow and noise-generation …

The slat represents an important airframe noise source as it extends over almost the entire
aircraft wingspan. Most studies of slat noise consider idealized geometries. However, for …

To ensure the aerodynamic performance of the slat in aircraft when retracted, it is necessary
to set rubber seals in the seam between the leading-edge slat and the fixed leading edge …

To study the noise reduction effect of a variable-bend slat, both experimental and numerical
investigations are carried out on a two-dimensional high-lift configuration with a stowed flap …

Slat noise experiments are sometimes performed to provide data for the validation of
numerical procedures. Under such circumstances, closed-section wind-tunnels, in contrast …

This paper introduces the Low Acoustic Noise and Turbulence (LANT) wind tunnel of the
Sao Carlos School of Engineering, University of Sao Paulo (USP-EESC), Brazil. The closed …

The leading-edge slat has been identified as a relevant noise source since the 1970's.
However, many issues regarding the noise generation mechanisms and the appropriate …

Air traffic has developed rapidly in the last decades. The noise generated from aircraft can
impair the health of passengers and airport residents, so it is necessary to reduce aircraft …

B theoretical formulations, as well as the complexity inherent to each of them, vary largely
among the techniques presented in the literature. Overall, these techniques apply to …
